Better multiplayer
Turrets can now be controlled
the multiplayer is
slightly better but its still absolute bullstuff since it totally breaks at speeds higher than 200 m/s
controllable turrets has been a thing for ages what are you on about
oh and you have to sit in a cryopod before logging off of a multiplayer server or else you lose everything
if the cryopod loses oxygen and/or power while you're gone you'll die instantly
crashing counts as logging off too
maxwell is more qualified to rant about how awful space engineers is than i am so he'll tell you more probably
